Sunshine-based metrics for Barbados in November. Primary: % of days ≥ 72°F with > 6 h of sunshine.
Period Warm & sunny (≥72°F, >6 h sun) Sample (n)
Early November
1st–15th		 97% n=120
Late November
16th–end		 98% n=120
Full month average 98% n=240
10.9 h median sunshine per day 92% of days exceed 8 h sunshine 68% of days see ≥ 1 mm rain — rain is not hidden
Comparison (old vs new): WMO-code “clear” bar: 6%. Sunshine-based “warm & sunny”: 98%. The 92-point gap is from brief afternoon convective storms that stamp the whole day as “rain” in the WMO code but leave the bulk of the sunshine untouched.

Bottom line

Barbados is a poor choice for sun in November: just 6% of days clear historically (n=240). March is the historically strongest month for sun here. The 8-year record is consistent — this is not a fluke bad stretch.
